[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1 This embodiment provides a precision filling device for rubidium and cesium materials, such as... Figure 1 and Figure 2 As shown, it includes: a transfer chamber 33, a first chamber 31 for placing multiple raw material tanks 1 and a second chamber 32 for placing target tanks 2, wherein the first chamber 31 and the second chamber 32 are connected to a vacuum system; In this embodiment, as Figures 1 to 3 As shown, the vacuum system includes a vacuum pump 22 and a cold trap 24. The vacuum pump 22 is connected to the cold trap through a pipeline. The cold trap 24 is connected to the first chamber 31 and the second chamber 32 through two branch pipelines. The two branch pipelines are respectively equipped with a first chamber valve 34 and a second chamber valve 35. When the first chamber 31 and the second chamber 32 need to be evacuated, the first chamber valve 34 and the second chamber valve 35 are opened to realize the connection between the vacuum system and the first chamber 31 and the second chamber 32. The transfer chamber 33 is equipped with a guiding device that connects the raw material tank 1 in the first chamber 31 and the target tank 2 in the second chamber 32. The guiding device includes a docking mechanism and a liquid guiding mechanism, such as... Figure 3 As shown, the docking mechanism includes a docking pipe 3 that is reciprocated and dynamically sealed to the first chamber 31, and a first linear drive mechanism 4 that can drive the docking pipe 3 to reciprocate. The liquid guiding mechanism includes a liquid guiding pipe 5 that is reciprocated and dynamically sealed to the docking pipe 3, and a second linear drive mechanism 6 that can drive the liquid guiding pipe 5 to reciprocate. The docking pipe 3 is sleeved on the outer periphery of the liquid guiding pipe 5, and an air inlet chamber is formed between the docking pipe 3 and the liquid guiding pipe 5. The air inlet chamber is connected to a gas source that can supply inert gas. In this embodiment, the inert gas is argon, and the gas source can be a steel cylinder. A guide seat is fixedly provided at the top of the first chamber 31, and a first sealing ring is fixedly provided inside the guide seat. The connecting pipe 3 and the guide seat are dynamically sealed through the first sealing ring. A second sealing ring is fixedly provided inside the connecting pipe 3. The connecting pipe 3 and the liquid guide pipe 5 are dynamically sealed through the second sealing ring. The inner wall of the connecting pipe 3, the outer wall of the liquid guide pipe 5 and the second sealing ring form an air inlet chamber with an open bottom end. Gas is introduced into the raw material tank 1 through the open bottom end. The liquid guide tube 5 is provided with a liquid guide tube switch valve 28, and one end of the connecting tube 3 is provided with a connecting tube switch valve 29. The first linear drive mechanism 4 can drive the connecting tube switch valve 29 to connect with the raw material tank switch valve 30 on the feed inlet of the raw material tank 1, so that the connecting tube switch valve 29 and the raw material tank switch valve 30 are sealed together. One end of the liquid guide tube 5 can be connected to the feed inlet of the target tank 2 in the second chamber. The second linear drive mechanism 6 can drive the other end of the liquid guide tube 5 to be inserted into the raw material tank 1. In this embodiment, the sight glass opening of the target tank 2, after the flange sight glass is removed, is used as a feed inlet, such as... Figure 3 As shown, a sealing ring is fitted on one end of the raw material tank switch valve 30 near the connecting pipe switch valve 29. The first linear drive mechanism 4 can drive the end of the connecting pipe switch valve 29 to move downward to press the sealing ring on the raw material tank switch valve 30 to achieve a sealed connection. This embodiment provides a precision filling device for rubidium and cesium materials. By setting up a vacuum system, the first chamber 31, which holds multiple raw material tanks 1, and the second chamber 32, which holds target tanks 2, can achieve a vacuum state. A first linear drive mechanism 4 and a second linear drive mechanism 6 respectively drive the connecting pipe 3 and the liquid guide pipe 5 to reciprocate, thereby enabling communication between the raw material tanks 1 and the target tanks 2 under vacuum. An inert gas source delivers inert gas to the raw material tanks 1 through the air inlet chamber between the connecting pipe 3 and the liquid guide pipe 5, causing the molten metal in the raw material tanks 1 to flow into the target tanks 2 under the pressure of the inert gas. In this way, the molten metal can be filled under air-isolated conditions, maximizing the purity of the metal and avoiding the risks associated with tipping operations.

[0019] Specifically, such as Figure 1 As shown, the first chamber and the second chamber are each equipped with an observation window 25, a pressure gauge 26, an inflation valve 37, an exhaust valve 38, a glove opening, and a chamber inlet and outlet. A glove is fitted over the glove opening, and the inflation valve 37 is connected to a gas source that can supply inert gas. like Figure 1 and Figure 4 As shown, it also includes a glove door 9 capable of sealing the glove opening and a chamber door 10 capable of sealing the chamber entrance and exit.

[0020] In actual use, the raw material tank 1 and the target tank 2 are placed into the chambers through the inlet and outlet of the first chamber 31 and the second chamber 32, respectively. After the chamber door 10 is closed, a sealed environment is formed inside the first chamber 31 and the second chamber 32. The operator observes the internal situation through the observation window 25 and operates through the gloves on the glove opening. The pressure gauge 26 is used to display the pressure inside the chamber.

[0021] When it is necessary to open the chamber doors 10 of the first chamber 31 and the second chamber 32 after vacuuming, the gas filling valve 37 is opened to fill the chamber with argon gas, and then the argon gas is discharged through the exhaust valve 38 to achieve vacuum breaking.

[0022] Specifically, such as Figure 3 As shown, a weight detector 11 is provided in the second chamber 32, and the target can 2 can be placed on top of the weight detector 11 to facilitate quantitative filling of the target can 2.

[0023] Preferably, such as Figure 2 As shown, it also includes an adapter 12, such as Figure 10 As shown, one end of the adapter 12 is provided with a feed pipe 123, and the other end of the adapter 12 is provided with a first discharge pipe 121 and a second discharge pipe 122. The adapter 12 has a cavity that can connect the first discharge pipe 121, the second discharge pipe 122 and the feed pipe 123. The inner diameter of the first discharge pipe 121 is larger than the inner diameter of the second discharge pipe 122. The feed pipe 123 is connected to the liquid guide pipe 5. The first discharge pipe 121 and the second discharge pipe 122 can be connected to the feed port of the target tank 2.

[0024] The first discharge pipe 121 and the second discharge pipe 122 can be used individually or together. When used together or when the first discharge pipe 121 is used alone, the molten metal can be quickly introduced into the target tank 2. When the weight of the molten metal filled in the target tank 2 is close to the specific weight required by the customer (for example, when the weight is 10% short), only the second discharge pipe 122 with a small diameter is used to fill the target tank 2, so as to ensure the weight accuracy through small flow filling.

[0025] Preferably, such as Figure 6 As shown, it also includes a first discharge valve 15 and a second discharge valve 16, which are connected to the first discharge pipe 121 and the second discharge pipe 122 respectively via hoses 36. Figure 6 Only the hose 36 connecting the first discharge valve 15 and the first discharge pipe 121 is shown in the figure. According to the weight of the molten metal filled in the target tank 2, the opening and closing of the first discharge valve 15 and the second discharge valve 16 are controlled, thereby controlling the outflow of molten metal in the first discharge pipe 121 and the second discharge pipe 122. The second chamber 32 is fixed with the first pipetting slide 17 and the second pipetting slide 18. The first discharge valve 15 and the second discharge valve 16 can slide back and forth on the first pipetting slide 17 and the second pipetting slide 18 respectively to approach or move away from the inlet of the target tank 2, thereby inserting into or moving away from the inlet of the target tank 2. In this embodiment, as Figure 8 and Figure 9As shown, the first pipetting slide 17 is provided with a sliding groove, and the first discharge valve 15 is provided with a slider that can slide along the sliding groove. The slider is provided with a hand-tightening bolt 39. Tightening the hand-tightening bolt 39 can lock the position of the slider. The sliding connection between the second pipetting slide 18 and the second discharge valve 16 is the same.

[0026] In this embodiment, a limiting baffle is fixedly provided on the outer periphery of the end of the first discharge valve 15 away from the hose 36 and the end of the second discharge valve 16 away from the hose 36. The limiting baffle can abut against the inlet of the target tank 2 to prevent the first discharge valve 15 or the second discharge valve 16 from being inserted into the target tank 2 too deeply. like Figure 6 As shown, the second chamber 32 is also provided with a first placement cylinder 19 and a second placement cylinder 20. The first discharge valve 15 and the second discharge valve 16 can be sealed to the first placement cylinder 19 and the second placement cylinder 20 respectively (for ease of understanding, Figure 6 The diagram simultaneously shows the states of the first discharge valve 15 and the second discharge valve 16 on the first placement cylinder 19 and the second placement cylinder 20, as well as their states on the first pipetting slide 17 and the second pipetting slide 18. In this embodiment, a sealing ring is provided at the top of the first placement cylinder 19 to seal the first discharge valve 15 and the first placement cylinder 19 after docking, preventing the residual molten metal on the first discharge valve 15 from being oxidized after the second chamber 32 is opened, thus affecting the purity of the molten metal subsequently filled. Figure 7 As shown, the first discharge valve 15 and the first placement cylinder 19 are connected by a quick-opening clamp, and the connection method of the second discharge valve 16 and the second placement cylinder 20 is the same as that of the first discharge valve 15 and the first placement cylinder 19.

[0027] Preferably, it further includes a heating system for ensuring that the internal temperature of the transfer chamber 33, the first chamber 31 and the second chamber 32 is greater than the melting point of the metal contained in the raw material tank 1.

[0028] In this embodiment, temperature sensors are provided in the transmission chamber 33, the first chamber 31 and the second chamber 32. The temperature sensors monitor the temperature inside the chamber, so that the controller controls the opening and closing of the heating system according to the temperature inside the chamber (a temperature threshold can be set, and the system will automatically heat when the temperature is below the threshold). like Figure 4 As shown, the heating system includes an electric heater 8 and a hot air blower 23. The air outlet of the hot air blower 23 leads to the transmission chamber 33. Electric heaters 8 are provided on the side walls of the first chamber 31 and the second chamber 32.

[0029] Preferably, the air intake chamber is connected to a gas source capable of supplying inert gas via an air intake pipe 27 coiled within the transmission chamber 33. The coiled air intake pipe 27 allows the inert gas to be fully preheated, preventing the molten metal from solidifying due to the low temperature of the inert gas. Figure 4 As shown, the intake pipe 27 is also equipped with a pressure reducer 7 to reduce the pressure of the inert gas; for ease of layout, the side wall of the connecting pipe 3 is provided with an interface for connecting the intake pipe 27, and the inert gas enters the intake chamber from the interface.

[0030] Specifically, such as Figure 5 As shown, the first linear drive mechanism 4 and the second linear drive mechanism 6 are both manual linear drive mechanisms (in practical applications, electric linear drive mechanisms or pneumatic linear drive mechanisms can also be used to achieve the drive). The manual linear drive mechanism includes a screw and nut mechanism, a pulley seat 47, a crank 41, a support 42 and a pulley shaft 43. The pulley seat 47 and the support 42 are fixed outside the transmission chamber 33. The crank handle 41 and the pulley shaft 43 are rotatably mounted on the support 42. The crank handle 41 is provided with a driving gear 44. One end of the pulley shaft 43 is provided with a driven gear 45, and the other end of the pulley shaft 43 is provided with a driving pulley 46. The driven gear 45 and the driving gear 44 are meshed with several transmission gears. The pulley seat 47 is provided with a rotatable driven shaft 48. One end of the driven shaft 48 is provided with a driven pulley 49 that is connected to the driving pulley 46. The other end of the driven shaft 48 is provided with a driving bevel gear 410. The lead screw 411 of the lead screw 411 is provided with a driven bevel gear 412 that meshes with the driving bevel gear 410. The lead screw 411 is provided with a lead screw nut. The connecting pipe 3 and the liquid guide pipe 5 are respectively provided on the lead screw nut of the first linear drive mechanism 4 and the lead screw nut of the second linear drive mechanism 6.

[0031] By turning the crank handle 41, the driving gear 44 is driven to rotate. The driving gear 44 and the driven gear 45 are driven by multiple transmission gears (the transmission gears are mounted on the gear shaft rotatably connected to the support 42). The pulley shaft 43 rotates accordingly, driving the driving pulley 46 to rotate. The driving pulley 46 drives the driven pulley 49 to rotate through the transmission belt, causing the driven shaft 48 to drive the driving bevel gear 410 to rotate. The driving bevel gear 410 drives the driven bevel gear 412 to rotate, causing the lead screw nut on the lead screw 411 to move vertically. The multi-stage gear transmission increases the torque, so that the manual linear drive mechanism can remain stationary when the operator does not turn the crank handle 41.

[0032] Specifically, such as Figure 5As shown, it also includes a guide rail 21 fixed outside the transmission chamber 33 and a first slide block 13 and a second slide block 14 slidably disposed on the guide rail 21; the first slide block 13 is fixed on the lead screw nut of the first linear drive mechanism 4, and the second slide block 14 is fixed on the lead screw nut of the second linear drive mechanism 6. The connecting tube 3 and the liquid guide tube 5 are respectively fixed on the first slide 13 and the second slide 14. The first slide 13 and the second slide 14 share the guide rail 21 to ensure the movement accuracy of the connecting tube 3 and the liquid guide tube 5.

[0033] Example 2 A process method for precise filling of rubidium and cesium materials, using the precision filling equipment for rubidium and cesium materials described in Example 1, is characterized by further including the following steps: S1: Open the chamber door 10, place multiple raw material tanks 1 into the first chamber 31, and place the target tank 2 into the second chamber 32; S2: Close chamber door 10 and evacuate the first chamber 31 and the second chamber 32 using the vacuum system; S3: Open glove door 9, the operator puts on the gloves at the glove opening, the operator drives the connecting pipe switch valve 29 to seal the connection with the raw material tank switch valve 30 through the first linear drive mechanism 4, opens the connecting pipe switch valve 29 and the raw material tank switch valve 30, drives one end of the liquid guide pipe 5 to be inserted into the raw material tank 1 through the second linear drive mechanism 6, removes the flange sight glass on the target tank 2, the other end of the liquid guide pipe 5 is connected to the sight glass opening of the target tank 2 through the first discharge valve 15, and opens the first discharge valve 15; S4: The gas source injects inert gas into the raw material tank 1 through the air inlet chamber, causing the molten metal in the raw material tank 1 to flow into the target tank 2 through the liquid guide pipe 5; S5: When the molten metal in raw material tank 1 has drained out and target tank 2 has not been filled to the required weight, the liquid guide tube 5 is pulled out from the current raw material tank 1 by the second linear drive mechanism 6, and the connecting pipe switch valve 29 is moved away from the raw material tank switch valve 30 of the current raw material tank 1 by the first linear drive mechanism 4, so as to manually move the position of raw material tank 1 and switch to another raw material tank 1. Repeat steps S2 to S4 until target tank 2 is filled to the required weight (when the weight of molten metal in target tank 2 is close to the specific weight required by the customer, the first discharge valve 15 should be closed and the second discharge valve 16 should be opened to continue filling). S6: After filling is completed, reinstall the flange sight glass, remove the first discharge valve 15 and the second discharge valve 16 from the first pipetting slide 17 and the second pipetting slide 18, and place them on the first placement cylinder 19 and the second placement cylinder 20 respectively for sealing connection. S7: Open the filling valve 37 to fill the chamber with argon gas, and then discharge the argon gas through the exhaust valve 38 to break the vacuum. Then open the chamber door 10 and take away the target tank 2.
